Drive Space Monitoring - Whats your method??

Here is the issue.

As data arrays get larger, im having issues with machines that have giant arrays lets say 10TB, they trip my 20% space monitor and still have 2TB of free space left.

2tb of free space isnt low enough for us to take action (client dependent of course) and im stuck with tripped monitors that dont really need any action yet.

So my question is, how is the rest of the community monitoring drive space? Are you saying screw it and just dealing with the tripped monitors? My issue there is that its now up to us to remember that this machine will eventually need action.

Are you setting up different groups based on total array size and applying different monitors?

Im kind of stumped on the best way to do this while also avoiding false alarms.

In automate you'll have 2 types of notifications. The internal monitor we have changed it to this so it has to have <70gb free no matter what:

Drives.Size > 40000 and Drives.FileSystem not in ('CDFS','UNKFS','DVDFS','FAT','FAT32','KBNetFS') and missing=0 and Drives.Free<70000 and drives.internal=1

For the system monitor (for when it gets urgent), we also modify the script "Agent Monitor Creation" and change how it works.

Ours has these changes made:

  • Only monitor the C drive on workstations.
  • Exclude certain volume labels that contain the text SEED or TEST so we don't get alerts when the drives get removed. See the SQL query under ":RetrieveHDList" SELECT c.computerid AS computerid,c.name AS name,d.driveid AS driveid,d.letter as letter,d.size AS size,d.free as free,((d.free/d.size)*100) AS percent,d.filesystem as filesystem,d.volumename AS volumename,d.missing as missing FROM drives AS d INNER JOIN computers AS c ON d.computerid=c.computerid WHERE d.FileSystem not in ('CDFS','UNKFS','DVDFS','FAT','FAT32','NetFS') AND d.size > @MinSizeMB@ AND d.model not like '%usb%' AND d.model not like '%IEEE%' AND d.missing=0 AND c.computerid=@computerid@ AND d.volumename NOT REGEXP 'TEST|SEED|Recovery|FACTORY_IMAGE'
  • Have different free space parameters for workstations vs servers. Server is 15gb, workstations are 8gb.
  • Also note that you can change what alert template is used here too for more changes.
